BioASQ 2021: Large-scale biomedical semantic indexing and question answering

This competition aims to improve the state of the art of semantic indexing for documents written in Spanish. This edition proposes to index not only scientific literature, but also clinical trials and patents to evaluate if well-known structured vocabularies can be used for other type of biomedical documents. The generation of automatic systems to index other documents would foster the interoperability of search queries and would be the first step towards unifying databases to include all available biomedical information by exploring cross-corpus training scenarios. The competition also introduces new possible metrics based on semantic similarity to assess the quality of the generated systems as well as the usability of the results to improve the efficiency of manual indexing tasks using predictive models and manual indexing tools.
